Echocardiographic findings in patent ductus arteriosus-associated infective endarteritis.

Background: Infectious endarteritis associated with patent ductus arteriosus (PDA-IE) is an uncommon complication in the era of antibiotics. However, it implies a clinical challenge in patients with a fever of undetermined origin; Two-dimensional transthoracic echocardiography (TTE) performs a fundamental role in diagnosis and follow-up.

Methods: A retrospective analysis was then made of the data of all patients admitted at our center with PDA-IE within 15 years, and a review of the literature regarding diagnosis, TTE findings, and treatment was performed.

Applicability of the Leiden Convention and the Lipton Classification in Patients with a Single Coronary Artery in the Setting of Congenital Heart Disease.

In single coronary artery (SCA) anatomy, all coronary tributaries arise from a single ostium, providing perfusion to the entire myocardium. Coronary classification systems can facilitate the description of SCA anatomy. Evaluation of the applicability of Lipton classification and the Leiden Convention coronary coding system in SCA.
